How far we've come from the days before Scorpio where everyone said it had no chance of doing 4K native at all.It is not impressive until we know the XB1 resolution. Normal if the game runs at 1080p, impressive if it runs at 900p.
To impossible to do 4K60
To it must do more than 6x the resolution of Xbox One titles to be considered impressive.
Quite a few goal posts have moved under a year that's fairly impressive; the next 2 years will be where we see X1X start to be really optimized by developers.
